Two weeks after returning home from traveling, a client presents to the clinic with conjunctivitis and describes a recent loss in the ability to taste and smell. The nurse obtains a nasal swab to test for COVID-19. Which action is most important for the nurse to take?

Teach the client to wear a mask, hand wash, and social distance to prevent spreading the virus.

Isolate the client from other clients, family, and healthcare workers not wearing proper PPE.

Report the COVID-19 result to the local health department according to CDC guidelines.

Explain to the client to inform others that they may have been potentially exposed in the last 14 days.

Answer and Explanation

The Correct Answer is B

Choice A reason: This is incorrect because teaching the client to wear a mask, hand wash, and social distance is not the most important action for the nurse to take. These are preventive measures that should be followed by everyone, regardless of their COVID-19 status.

Choice B reason: This is correct because isolating the client from other clients, family, and healthcare workers not wearing proper PPE is the most important action for the nurse to take. This is to prevent transmission of COVID-19 to others who may be at risk of severe complications or death.

Choice C reason: This is incorrect because reporting the COVID-19 result to the local health department according to CDC guidelines is not the most important action for the nurse to take. This is a legal and ethical obligation that should be done after confirming the diagnosis, but it does not have an immediate impact on the client's health or safety.

Choice D reason: This is incorrect because explaining to the client to inform others that they may have been potentially exposed in the last 14 days is not the most important action for the nurse to take. This is a moral and social responsibility that should be done as soon as possible, but it does not address the urgent need of isolating the client from potential sources of infection.

Correct Answer is ["100"]

Explanation

To answer this question, we need to find the rate of infusion in milliliters per hour (mL/hr) that will deliver 1 liter (1000 mL) of 0.9% sodium chloride, USP intravenously (IV) over 10 hours. We can use the following formula to calculate the rate:

Rate(mL/hr)=Volume(mL)/Time(hr)

Plugging in the given values, we get:

Rate(mL/hr)=1000mL/10hr

Simplifying, we get:

Rate= 100mL/hr

A. The humoral immune response lacks B cells that form antibodies and opportunistic infections result. B. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages. C. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms. D. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.

Correct Answer is B

Explanation

Choice A reason: This is incorrect because the humoral immune response involves B cells that produce antibodies against specific antigens. However, AIDS affects the cellular immune response, which involves T cells that activate other immune cells and directly kill infected cells.

Choice B reason: This is correct because AIDS is caused by human immunodeficiency virus (HIV), which infects and destroys CD4+ T cells, also known as helper T cells. These cells are essential for initiating and regulating both humoral and cellular immunity. Without enough CD4+ T cells, the body cannot mount an effective response against pathogens, especially opportunistic infections that take advantage of a weakened immune system.

Choice C reason: This is incorrect because bone marrow suppression of white blood cells is not a direct consequence of AIDS. However, some drugs used to treat AIDS, such as zidovudine, may cause bone marrow suppression as a side effect.

Choice D reason: This is incorrect because exposure to multiple environmental infectious agents does not cause AIDS. However, people with AIDS are more susceptible to infections from various sources due to their impaired immune system.
